Today, it is typical to, for example, have an 8-layer depth conversion model, where each layer is assigned one of three types of lines (as noted below). What if, instead of being limited to the standard layer-cake approach, that you could quickly and easily create a detailed 800-layer model at log level resolution?
This is what we’re in the process of developing and we are excited to give you a preview of our brand new LogToVolume software which is scheduled for release in the autumn of this year.
Next Generation Depth Conversion Software
You might consider LogToVolume to be next generation depth conversion software, as it will provide you with capabilities that utilise the computational power of today/tomorrow and performs in a way that has not been operationally efficient historically.
With respect to depth conversion, presently the practice is to divide your data into a vertical layer-cake model and apply a depth conversion function to each layer to describe the velocities of each geological unit. This would either be classified as i) a straight line at an angle to represent increasing/decreasing velocity changes with increasing depth, where a V0K method would be used, ii) a straight vertical line to represent a constant interval velocity, or iii) a curved line to represent the asymptotic velocity changes that would perhaps be represented by the Faust formula.
The revolution that LogToVolume will bring to the industry is that it propagates the velocity information contained within your logs throughout the volume, while still conforming to the conventional interpreted layering regime. “This is significant as it will improve the accuracy of your velocity prediction versus conventional methodology”.
You have the option to select whether the velocities are ‘Cut from Top’, where they are parallel with the base of the layer, ‘Cut from Base’ where the velocities are parallel with the top of the layer, or you can select ‘Stretch and Squeeze’ where the velocities are proportional as a layer thickens or thins.
Velit / VelPAK
This new technology will complement our current Velit/VelPAK software as it requires reasonable log coverage across your survey area to make its computations competently. Velit/VelPAK will still be the tool of choice when it comes to creating accurate velocity models from sparse data.
Between now and the product’s launch date, we will dive deeper into the functionality of LogToVolume, including the construction of the Framework of the model, your control over how the logs are spread, the depth conversion aspect of the software and its mapping capabilities. You will see how the design philosophy of the software is Wizard-based, making it operationally efficient and easy to use for any level of experience.
